History Spider T is an iron hull Humber sloop built in 1926 at Warrens Shipyard, New Holland, with a Gardner diesel engine, 200 hp. She was built for cargo carrying and worked as such until 1972. Later, she was sunk, refloated and used for the Rotherham Police Community Project. The present owner bought her in 1994 from the Sobriety Centre, Goole.
